A blog post authored by our colleagues at T3DMC highlights the changing landscape of metrology, where 3D scanning has emerged as the preferred method for obtaining accurate 3D data across a wide range of industries for various applications.
The data captured by 3D scanning is full field, covering the entire surface of the component, thereby providing a comprehensive inspection and analysis of the entire part. The reports generated using 3D scanning provide powerful data that can be used to evaluate the performance of the component across the complete surface.
Compared to traditional single-point tactile measurements, the full surface data contains far more detailed information that can be presented in a simple and easy-to-understand format. Moreover, 3D scanning offers vast improvements in the measurement process, almost complete removal of fixture requirements, significantly increased flexibility, and portability of measurement.
The scan data can be used to create a detailed report that can highlight the deviation of complex freeform surfaces, geometric elements, and GD&T features against the CAD nominal or the master sample.
3D scanning systems have a further advantage over traditional CMM equipment as parts can be measured without the need for fixtures, and the scanning system can be brought to the part rather than the part being brought to the measurement device and fixed into position.
3D scanning equipment is portable in most cases, enabling components, machines, fixtures, tooling, etc., to be measured in situ, which is not possible for most traditional CMM equipment.
3D scanning systems are now in use across many industries, particularly in the Automotive and Aerospace Industries, where manufacturers are well known for applying exacting standards of accuracy on both their own systems and that of their respective supply chains.
Finally, 3D scanning offers comprehensive data capture from the system, which is particularly relevant as many industries progress towards Industry 4.0 and the need for full-field measurement data for all parts incorporated in either manufacturing or assembly situations.
The data produced from 3D scanning can be used for either batch or continuous production of components and can be used as part of virtual assembly simulations, which form a key element of developing “factories of the future.”
Experts predict that the need for full field data will cascade down the supply chain for all parts used across a range of industries to ensure that consistent quality and repeatability are achieved, reducing the risk of failures to Six Sigma levels.
